Based on the analysis of long-chain normal paraffin selective isomerization reaction mechanism, a new molecular sieve LKZ with TON structure has been successfully synthesized and the noble metal catalyst WSI prepared with the modified molecular sieve.

The quantitative relation between the surface tension and the number of carbon atoms of normal paraffin hydrocarbons at different temperature are studied systematically in this paper.

The degradation ability and uptake modes of Long-chain alkane-degrading bacteria were investigated.

Nano-sized Beta zeolite was successfully synthesized,its properties were analyzed,and its performance in the hydrocracking of long-chain alkane was investigated.

The result showed that the impurities in crude phytosterols from soybean oil deodorizer distillate and rapeseed oil deodorizer distillate were long chain alkane and wax, respectively.

The characteristics of difunctional modified polysiloxane,such as amido and polyether modified polysiloxane,amido and amid modified polysiloxane,amido and long chain alkane modified polysiloxane,epoxy and polyether modified polysiloxane,carboxy and long chain alkane modified polysiloxane were introduced,their synthesis process,application were described,and their prospects were predicted.

STM observation shows that long chain alkanes increase the adsorption stability of organic molecules.

Effect of alkaline-earth promoters on the catalytic properties of supported PtSn/γ-Al_2O_3 catalysts for long-chain paraffin dehydrogenation;

The influence of alkali metal ion promoters on the catalytic properties of Pt-Sn/γ-Al 2O 3 catalysts for the long-chain paraffin (C 10 ～C 13 ) dehydrogenation has been studied by H 2 chemisorption, infrared spectroscopy (IR), thermogravimetry (TG), temperature-programmed reduction (TPR) and microreactor testing.
